Leucocytozoon (Haemosporida; Leucocytozoidae) of the Falconiformes
Canadian Journal of Zoology, 1977Falconiform-inhabiting species of Leucocytozoon are reviewed and a checklist of Falconiformes known to harbor Leucocytozoon is included. Morphological measurements were made from 11 falconiform species to examine the interspecific and intraspecific variations. These formed the basis for the redescription of gametocytes of L. toddi Sambon.

Sporogonic Development of Leucocytozoon smithi
The Journal of Protozoology, 1992The sporogonic development of Leucocytozoon smithi in its black fly vector was studied by light and electron microscopy and was compared with that of other haemosporidians. Within 18 to 24 h after ingestion of gametocytes by black flies, ookinetes passing through the midgut epithelium were observed.

Leucocytozoon Disease of Turkeys
World's Poultry Science Journal, 1977Leucocytozoon disease of turkeys, like that of other avian species, is caused by a blood protozoan that has a complex life cycle involving development in the bird (asexual) and in an intermediate h...

Schizogonic Development of Leucocytozoon smithi
The Journal of Protozoology, 1992ABSTRACT The schizogonic development of Leucocytozoon smithi in the liver of experimentally infected turkey poults was examined by electron microscopy. Following intraperitoneal injection, sporozoites migrated to the liver and entered hepatic cells to become intracellular trophozoites.

Cryopreservation of Leucocytozoon caulleryi Sporozoites
The Journal of Protozoology, 1988ABSTRACTLeucocytozoon caulleryi sporozoites that had been stored at ‐ 196° C or ‐80° C for 6 or 12 months in Eagle's minimum essential medium or Medium 199 supplemented with 5% glycerol and 10% chicken serum showed infectivity to chickens. Glycerol at a concentration of 10% and dimethyl sulfoxide at 10% and 5% were found to be ineffective ...

Leucocytozoon spp : Leucocytozoonosis
2023La leucocytozoonosis es una parasitosis de las aves producida por especies de Haemosporida (Apicomplexa) pertenecientes a la familia Leucocytozoidae, de ciclo indirecto y de distribución mundial, transmitida por vectores dípteros hematófagos. Algunas especies han sido asociadas a brotes de enfermedad, e incluso muertes en aviarios, zoológicos y granjas

Crystalline inclusions in Leucocytozoon simondi
Canadian Journal of Zoology, 1971Vacuoles have been observed in haemosporidian ookinetes fixed in methanol and stained with Giemsa's (5) (Fig. 1). Electron microscopy studies on sporogony of Leucocytozoon simondi indicate that the "vacuoles" contain accumulations of crystalline material (8) (Fig. 3).

Anemia in Ducks Infected with Leucocytozoon simondi*†
The Journal of Protozoology, 1966SYNOPSIS. Thirty‐four white Pekin ducklings were used to study the anemia associated with infection by Leucocytozoon simondi.The first appearance of gametocytes in the peripheral blood, as detected by thin smears, marked the onset of anemia. This anemia lasted for the duration of the initial parasitemia, usually reaching a low point early in the ...

Morphological study of microgametogenesis of Leucocytozoon simondi
Journal of Ultrastructure Research, 1970The fine structure of the microgametocytes and microgametogenesis of Leucocytozoon simondi , a parasite of ducks and geese, was studied and compared to those of the related genus Plasmodia . The morphology of the microgametocyte of L. simondi is identical to that of avian malarial parasites.
